Description

  

  erfahren zur Herstellung eines     metallhaltigen        Farbstoffes.       Es     wurde    gefunden, dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den Farbstoff aus     diazotiertem        4-Chlor-2-          amino-l-phenol    und     f-Naphthylamin    in       Gegenwart    von     Alkalien    mit     kobaltabgeben-          den    Mitteln behandelt.  



  Der metallhaltige Farbstoff löst sich in  Wasser und Natronlauge schwer mit blau  violetter und in konzentrierter Schwefelsäure  mit violetter Farbe. Aus der     tiefblauviolett     gefärbten Lösung in     Zapon-    oder     Acetyl-          zelluloselack    erhält man auf geeigneten Un  terlagen tiefschwarze Überzüge von hervor  ragender Lichtechtheit.  



  <I>Beispiel:</I>  5,95     Gewichtteile    des     Farbstoffes    aus       diazotiertem        4-Chlor-2-amino-l-phenol    und       ss-Naphthylamin    werden in 500 Teilen Was  ser und 5 Teilen Natronlauge von 36       B6     aufgekocht und mit einer aus 2,38 Teilen  kristallisiertem     Kobaltchlorür    und der nöti  gen Menge Natronlauge erhaltenen Kobalt-         ogydhydratsuspension    einige Zeit am Rück  flusskühler zum Kochen erhitzt.

   Hierauf,  wird die vollständig ausgeschiedene     Kobalt-          verbindung    des Farbstoffes     abfiltriert,    aus  gewaschen und getrocknet.



  experienced in the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye composed of diazotized 4-chloro-2-amino-1-phenol and f-naphthylamine is treated with cobalt-releasing agents in the presence of alkalis.



  The metal-containing dye dissolves poorly in water and caustic soda with a blue-violet color and in concentrated sulfuric acid with a violet color. The deep blue-violet colored solution in zapon or acetyl cellulose varnish gives deep black coatings of excellent lightfastness on suitable substrates.



  <I> Example: </I> 5.95 parts by weight of the dye from diazotized 4-chloro-2-amino-l-phenol and ß-naphthylamine are boiled in 500 parts of water and 5 parts of 36 B6 sodium hydroxide solution and mixed with one 2.38 parts of crystallized cobalt chloride and the necessary amount of sodium hydroxide solution obtained cobalt ogydhydratesuspension heated to boiling for some time on the reflux condenser.

   The completely separated cobalt compound of the dye is then filtered off, washed off and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines metall haltigen Farbstoffes, dadurch gekennzeich net, dass man den Farbstoff aus diazotiertein 4-Chlor-2-amino-l-phenol und ss-Naphthyl- amin in Gegenwart von Alkalien mit einem kobaltabgebenden Mittel behandelt. Der metallische Farbstoff löst sich in Wasser und Natronlauge schwer mit blau violetter und in konzentrierter Schwefelsäure mit violetter Farbe. PATENT CLAIM: Process for the production of a metal-containing dye, characterized in that the dye is treated from diazotized 4-chloro-2-amino-1-phenol and ß-naphthylamine in the presence of alkalis with a cobalt-releasing agent. The metallic dye is difficult to dissolve in water and sodium hydroxide solution with a blue-violet color and in concentrated sulfuric acid with a violet color. Aus der tiefblauviolett gefärbten Lösung in Zapon- oder Acetyl- zelluloselack erhält man auf geeigneten Un terlagen tiefschwarze Überzüge von hervor ragender Lichtechtheit. The deep blue-violet colored solution in zapon or acetyl cellulose varnish gives deep black coatings of excellent lightfastness on suitable substrates.
